I may be mistaken in > this though. I think you're talking about a third type of machine, which is a grinder. 1. Graders have a blade which is between the front and rear wheels. The blade can swing around, move left and right, and up and down as well as tilt. 2. Scrapers are usually articulated and have an adjustable opening at the front of the scraper bucket. They also have a movable plate in the bucket that pushes the dirt out, thus giving them the ability to move huge quantities of earth around a job site. 3. Grinders (or whatever you want to call them) have the ability to tear up asphalt roads and grind up the bits. SOme just recycle the asphalt in place to create a new roadbed, others take the ground material off on a conveyor to a waiting truck. Either way, there are LOTS of very specialized bits of construction machinery waiting for expert Technicificaiton Cheers, Ralph Hempel - P.Eng -------------------------------------------------------------------- Check out pbFORTH for LEGO Mindstorms at: <http://www.hempeldesigngroup.com/lego/pbForth> Buy "Extreme Mindstorms: an Advanced Guide to Lego Mindstorms" <http://www.amazon.com/exec/obidos/ASIN/1893115844/hempeldesigngrou> -------------------------------------------------------------------- Reply to: rhempel at bmts dot com --------------------------------------------------------------------

(...) If you're talking about the machines used to "refresh" asphalt freeways, I think they'd be a good subject for Technic -- they already look like Technic creations. Steve (24 years ago, 25-Jan-01, to lugnet.technic)

(...) Innuendo noted :-) The funny thing is that I've never really "groked" graders, to use a phrase from a previous thread. It was only recently that I had any idea how they actually worked! I suspect this is probably because I've seen plenty of (...) (24 years ago, 24-Jan-01, to lugnet.technic)
